# Krovu

> Krovu is a workout tracker for iPhone and Apple Watch, with a web app at krovu.app for logging and reviewing training on a computer. It logs strength sessions set by set, runs HIIT and rest timers, detects personal records, and draws accumulated training volume onto a muscle heatmap. The muscle heatmap is free on every tier.

Krovu is made for people who lift and want their own numbers to be honest: previous
performance is pre-filled on every set, warm-ups are excluded from volume and personal
records, and estimated one-rep max is only shown where the formula still means something.

## Availability

Krovu has not yet been released on the App Store. The iPhone app is in development and the listing is not live; there is no download link to give out yet.

## Tiers

- **Free** — workout logging, HIIT and rest timers, the muscle heatmap, personal records
  and streaks, the social feed, and the Apple Watch app. Free permanently, not a trial.
- **Pro** — everything in Free, plus nutrition photo logging with macros, unlimited
  routines, full history beyond 90 days, advanced analytics and 1RM tracking, and progress
  photos and measurements.
- **Coach** — everything in Pro, plus adaptive AI training plans, on-device form check,
  guided avatar sessions, AI diet plans, and weekly reviews.

Pro and Coach are auto-renewing subscriptions sold through the Apple App Store and billed
to an Apple ID. Krovu does not take payment on the web; krovu.app has no checkout.

## Platforms

iPhone (iOS 18 or later) and Apple Watch, plus a web app at krovu.app/app for logging and
statistics. An Android app is a later phase of the roadmap with no announced date. iPad,
macOS and visionOS are not planned.

## How the numbers are defined

- Training volume is the sum of weight x reps over working sets. Warm-up sets are excluded
  from volume and from personal records.
- Estimated one-rep max uses the Epley formula, weight x (1 + reps / 30), and is shown only
  for sets of 12 reps or fewer.
- The muscle heatmap credits each working set to a primary muscle group at full volume and
  to each secondary group at half. The colour scale is relative to the user's
  hardest-trained group over the period shown.
- A streak counts consecutive ISO weeks, Monday to Sunday, containing at least one
  completed workout. One streak freeze per calendar month is applied automatically.
- Everything works offline. Reads and writes go to local storage first and synchronise when
  a connection is available.
